Mixed Feelings about Dial-a-Bed

My brother ordered two beds online on 25 November 2022 from Dial-a-Bed. The beds were of the same type and were to be delivered at two different addresses. The delivery time according to Dial-a-Bed is 2-3days. One bed was delivered within 48hrs, which is commendable. There other bed has not been delivered and there is no communication from Dial-a-Bed as to when it will be delivered. I called them on 05 December 2022 and they indicated they couldn't deliver because they were out of stock, but the stock has since been replenished and the warehouse will call to arrange delivery. No one has called from the warehouse. I called the customer service line again on 07 December 2022 and it rang unanswered for the whole day. They also don't respond to emails. This is very bad customer service by Dial-a-Bed. If they don't have stock, why don't they communicate with their customers? It's the least they can do.

All I need is for the remaining bed to be delivered as it has been paid for in full, including the delivery cost
